Welcome and thank you for your interest in Pacific Synthetic Oil and Lube. We are Tuija and Michael Cassidy and are located in Portland Oregon. My father Bill Multanen started as an Amsoil Dealer in 1976 in Lancaster California and became a Direct Jobber by 1977.

We worked together many years spreading the news about Amsoil’s inovation. Back in those days I remember potential clients telling us that they didn’t want “plastic” in their engines. Today that’s all changed with today’s auto manufactures requiring synthetic lubricants in the engines they produce. We look forward to speaking with you and helping you with your lubrication needs.
